DUAL-INTERFACE HYBRID METAL SMARTCARD WITH A BOOSTER ANTENNA OR COUPLING FRAME
First Claim
1. A dual-interface metal hybrid smartcard comprising:
- a plastic card body (CB);
a metal slug (MS) disposed in the card body; and
a booster antenna (BA) disposed in the card body comprising a card antenna (CA) component disposed around a peripheral area of the card body, a coupler coil (CC) component disposed at an interior area of the card body around an opening (OP) for receiving an antenna module (AM) or transponder chip module (TCM), and optionally an extension antenna (EA) component extending across another interior area of the card body.

Abstract
A dual-interface metal hybrid smartcard comprising a plastic card body (CB); a metal slug (MS) disposed in the card body; and a booster antenna (BA) disposed in the card body. The metal slug may have a surface area which is at least 50% of a surface area of the card body, and may comprise titanium or alloys thereof. A antenna chip module (AM) having an antenna (MA) and contact pads (CP) may be disposed in an opening of the card body. The metal slug may comprise two or more separate metal slug components (MS-1, MS-2), which may overlap one another or which may be disposed at different locations in the card body (CB), without overlapping one another. The first metal slug component (MS-1) may be disposed around a peripheral portion of the card body (CB) as an “open loop” discontinuous metal frame around (external to) the booster antenna (BA). The second metal slug component (MS-2) may be disposed internal to the card antenna (CA) component of the booster antenna (BA).
